Alphatax Provisioning Implementation Services & Support
Alphatax Provisioning, the Tax Systems tax provision software formerly known as Tax Proof, implemented by people who have prepared group tax provisions themselves. Osprey Consulting is an Alphatax partner: a tax pack for every entity, the return to provision, the checks and the group number built in. More of the Alphatax range will follow as we add it.
From local tax pack to group provision
One company's pack from the setup questions to the closed, locked pack, then fifteen packs in five currencies agreeing to one group number. Silent, with the steps captioned on screen, from the demo group we built in Alphatax Provisioning.
A provision made of packs, not workbooks
One pack per entity, per period
Every reporting entity gets a tax pack: a fixed sequence of schedules from the setup questions and tax rates, through permanent and temporary differences, to deferred tax, the P&L tax charge, the effective tax rate reconciliation and the entries for the ledger.
Packs that fit the entity
Eleven setup questions decide which schedules each pack shows. A simple entity answers no to most of them and sees a short pack; a complex one sees return to provision, tax losses, equity, credits and uncertain positions.
Return to provision, built in
Key the filed return against last year's provision and the pack shows every difference and carries the adjustment forward, so the prior year adjustment is worked, not estimated.
Checks before sign-off
A financial system check against the ledger, an error check that clears as the input is corrected, and a review path with reject or close. A closed pack is locked.
The group number
Packs consolidate in the group currency with the period's FX rates, and the group effective tax rate reconciliation comes out ready for the accounts.
Five phases
The design is agreed before the build, the prior year is recreated before anything goes live, and your team prepares the live period with our support as needed. By the roll forward it is yours.
Discovery and design
Entities, jurisdictions, currencies, the consolidation tree, the category mapping to your chart of accounts, the users and the review path, written down and signed before anything is built.
Blueprint build
The group structure, categories, account references, trial balance upload templates and users, built from the signed design and checked line by line by a second pair of eyes.
Prior year recreate
The entities set up and the prior period recreated in Alphatax Provisioning, from your own trial balances and the provision you have already signed. It validates the design against known figures, and it gives go-live its structure and opening balances.
Close and roll forward
This is go-live. The first live period prepared by your team, with our support as needed: setup questions per entity, data in by upload or import, every pack to ready-for-review with the checks clear, entity packs and the consolidation closed, the figures agreed to the tax note.
Post-implementation support
The year-end question, the new entity, the rate change, training for new joiners and cover while you recruit. Direct to the people who built it, not a helpdesk.
Alphatax Provisioning: questions we are asked
Is Alphatax Provisioning the same solution as Tax Proof?
Yes. Tax Proof was renamed Alphatax Provisioning in 2026. It runs on TaxSuite, Alphatax's cloud platform, and the vendor's guides still use the old name.
Can you bring in our existing provision data?
Yes. Opening positions, prior-year figures and trial balances come in through the solution's upload templates and data import, and we build the templates so the mapping from your chart of accounts is done once.
Who runs it after go-live?
Your team. Preparers complete packs, reviewers close them, and your administrators hold the structure. We document the set-up, train on your own environment, and stay available for the year-end questions.
Do you implement AlphataxCT and the other Alphatax solutions?
Provisioning first. Alphatax corporation tax compliance and the rest of the Alphatax range will follow as we add them; this page will say when.
Thinking about Alphatax Provisioning, or already on it?
Thirty minutes is usually enough to say whether it fits, how long the first period takes, and what we would need from your team.
